PASSENGER-DRIVER TELEPHONE SIGNAL SYSTEM FOR VEHICLES.

Specification of Letters Patent.

Application filed January 27, 1910. Serial No. 540,409.

T all whom it may concern) Be it known that I, HERMAN G. PAPE, a

signaling apparatus for closed body vehi-.

, cles such as landaus, landaulettes, limousines, victorias, town cars,cabs, taxicabs, etc., whereby the occupant or passenger can signal tothe driver or chauifeur in order to attract his attention and thenconvey a message telephonically in giving directions, askinginformation, etc, and whereby thea driver or chaufleur can respondby'speaking through a direct audible device such as a tube orsound-amplifying horn.

The invention has for one of its objects to provide an appliance of thischaracter which is of extremely simple and inexpensive construction,thoroughly reliable and eflicient in use, and so arranged and designedas to be conveniently operated.

Another object of the invention is the provision of a speaking tube orequivalent device which passes through the body of the vehicle .at apoint close to the driver whereby he can place his ear or mouth to itfor reoeiving a message or conveying one through the tube, together witha sound-reproducing device which can be energized by acircuitinterrupter or vibrator for signaling, or by a telephonetransmitter when t e occupant .desires to speak to the driver, thearrangement and combination of said instrumentalities being such thatthe sounds can be conveyed distinctly without any great efiort on thepart of the occupant or passenger and without leaving the seat.

With these ob'ects in view and others, as will appear'as t e descriptionproceeds, the invention comprises the various novel features ofconstruction and arrangement of partsv which will be more fullydescribed,

hereinafter andset forth with particularity in the claims appendedhereto.

the closed-in body of an automobile or other vehicle for which thepresent signal and speaking system'is especially designed. At somesuitable partof the body, where it is conveniently accessible to thechauffeur, is a speaking tube or direct sound conductor designatedgenerally by B, which passes through the front wall of the body in suchposition that the outer end of the tube will be close to the ear of thedriver; The device B is composed, in the present instance, of inner andouter tubular trumpet-shaped members 1 and QHthat are connected togetherby a coupling 3 passin through the front Wall 4 of the vehicle be y, theouter member B forming a combined ear trumpet and mouth piece for use bythe chauffeur, while pants within the vehicle. The part 3 is a Y-coupling' into two branches of which the trumpets 1 and 2 fasten, whilein the third branch, a sound-reproducing device, designated generally byC, is fitted. This device C is of any approved construction, such forinstance as that disclosed in my prior Patent No. 800,677, and isintended to be used for giving out -a signal when the chaufleursattention is to be directed, or to reproduce the f speech of theoccupant in conveying, a mesv sage to the chauffeur, and the part 2 orouter horn of the direct sound conductor B serves Referring to t-hedrawings, A designates as an amplifying means for the sound wavesgenerated by the device 0. v

The sound-reproducing device G cons sts of a diaphragm 4 arranged in asuitable chambered casing 5 that has a nipplefi com nected with theY-coupling 3, and this diaphragm is vibrated by an electro-magnet 7which has an armature 8 connected with the diaphragm," the winding ofthe electro-magnet being connected with the binding posts 9 and'9 towhich the wires 10 and 10 are respectively connected. An intermittentcurrent can be passed through the electro-magnet of the sound reproducerso as to vibrate the diaphragm, which will set up a buzzing soundtoserve as a signal for attracting the attention of the chauffeur, andby use of a telephone transmitter, an undulatory current of varyingamplitudes will be .sent through the magnet to cause the diaphragm torespond and set up speech vibrations which will be transmitted to thechaufieur.

r Fig. 9 shows the various instrumentalities used in connection with thesound-reproducmg device and circuit connections. The wires 10 and 10form the signal and telephone circuit connections, the current beingderived from a battery or other suitable source. A transmitter 13 of anyapproved construction is connected by the wires 14 and 15 with the wire10 and battery 11. These wires 14 and 15 are arranged as a cordconductor so that the transmitter can be conveniently manipulated andsaid transmitter, which may be of the watch case type, has a handle 16through which the wires 14 and 15 pass to the usual coil in thetransmitter.

The circuit through the transmitter is'n0r-' mally opened, and when thetransmitter is to be used, the circuits must be closed, and

' for this purpose, a push button or equivalent device is arranged,preferably, on th'e handle, 16, so that the button can be pressed whilegripping the transmitter handle. In the present instance, thepush buttonor circuit closer consists of a spring 17 fastened on the handle andconnected with the wire 15 and provided with a contact pin 18 thatis'adapted'to engage a. contact strip 19 fastened on the handle andconnected with the coil of the transmitter. Thus, by pressing the spring17, the contacts 18 and 19 are engaged so that current will flow throughthe transmitter, and upon vibrating the diaphragm of the transmitter bythe voice directed against it, anundulatory current will be ducingdevice which will be audible a articulate speech to the chauffeur.Arranged in shunt relation to the transmitter is a vibrator or circuitinterrupter 20 of any approved construction which has tion in thediaphragm of the. sound-reproone bindin post 21 connected by a wire 22 wththe wire 10, and the other binding post 23 connected by a wire 24= tothe side of the battery to which the wire 15 is con- I nected, the wire24 being provided with a normally-openpush button'25. The circuitinterrupter consists of'magnet coils 26 that button 25, current Wlllture 27 the movement of which operate on an armature 27 that carries aspring contact 28, which contact normally engages a relatively fixedcontact '29, and the coils 26 are connected, respectively, to thebinding post 21 and spring contact 28,. while the contact 29 isconnected by a wire 30 with the binding post 23. Bridging the contacts28 and 29 is a condenser 31 connected by wires 32 and 33 with the saidcontacts, so as to prevent excessive sparking between the latter duringthe operation of the interrupter. Upon fressing the push iibw throughthe coils of the interrupter and attract the armawill cause the contact28 to separate from the contact 29, thereby interrupting the current anddeenergizing the magnet so that the armature' will return to normalposition. and again'close the circuit by en aging the contact 28.withthe contact 29. n this manner, the circuit will be opened and closedin rapid succession by the interrupter so as to cause an intermittentcurrent to flow through the sound-reproducing device C, and as aconsequence, a buzzing sound will be emitted through the outer horn 2for at tracting the attention of the chaufieur. By reference to Fig.1,it ,will be observed that the push button 25 is located within theclosed body of the vehicle at a point conveniently within reach of theoccupant, and the transmitter 13 is arranged ad acent the push bpttonand is normally held in a pocket 34 or equivalent device so as to be ogout of the way. v

' The battery 11 and interrupter 20 may be t installed at anyconvenient, oint on the vehicle, as under the seat, at t e. dashboard orother place found most desirable by the 5 formed bythe two horns 1. and2vis always, 10
